If the download permission is allowed, you can download some or all of the files and folders in a data room at once. Here’s how you can bulk download in a data room:
Log on to your data room.
Click Shift + Select files and folders you want to download.
Once the download has finished, you will get a zip file containing the files and folders you’ve selected. The folder structure will remain the same.
Note that for data room owners, you can choose to download the files in its original format (Download As Owner) or with watermark (Download as Viewer/Contributor). Read more about it here.
